Description
The application is Chinese invention application (denomination of invention: for feeding the apparatus and method of to carry out pasteurize to the milk of newborn animal, the applying date: on March 19th, 2010; Application number: divisional application 201080018378.4).
Technical field
The present invention relates in general to fluid disinfection systems, and relates more specifically to the apparatus and method for carrying out pasteurize to the milk and colostrum of feeding newborn animal.
Background technology
The newborn animal that dairy products gather in factory feeds newborn animal with from (" the waste product ") milk that can not sell collected from the cow there that main drove is rejected because of medical science or other reason.Although feed the milk that can not sell to milk plant newborn animal seem that to milk plant operator be economical, there is such risk, namely infectious agent can directly be propagated from the mammary gland of cow by milk or effluent (shed).Other pathogen can be deposited on milk from ight soil or dirt, or the breeding in the milk that can never suitably refrigerate or store produces.
In order to reduce such risk, preferably milk or colostrum milk before feeding to newborn animal is being carried out pasteurize.Pasteurize in already known processes comprises: milk is heated to target temperature to kill objective microbe; With this temperature a period of time of maintenance.Pasteurize milk specification defines two kinds of different pasteurization methods: 1) under 145 ℉ the batch pasteurization of 30 minutes (low temperature is long-time, i.e. LTLT), or 2) under 161 ℉ between the high temperature, short time of 15 seconds pasteurize (HTST) (usually using continuous flow process).Heat and keep temperature to make bacterial concentration alive become the reduction of the order of magnitude higher than target temperature.But some thermoduric bacterias can withstand this technique.In addition, in the low-quality milk with very high bacterial concentration, some pathogens also can withstand pasteurization process.
For killing concerning the harmful bacterium of newborn animal as Escherichia coli, Bacillus cercus and salmonella, pasteurize be desirably and be required sometimes.If milk is keeping at least 30 minutes higher than 145 ℉, then these bacteriums close to 100% are successfully being killed in the pasteurize being heated to 145 ℉.A research shows, can use the lower temperature of 120 ℉, but this temperature must be maintained to few 60 minutes.
Once through pasteurize, milk can be bottled, freezing, storage, then reheat the temperature of breast-feeding to 100 ℉ ~ 110 ℉.Without the need to storage through the milk of pasteurize, because at milk through overheated pasteurize and after being cooled to supplying temperature, it is easier to utilize and can directly feeds to newborn animal.
In addition, feed in newborn animal is born two hours to colostrum and again feed in birth 12 hours to.Collecting colostrum cow soon after calving, and colostrum comprises the carbohydrate of rather high concentration, protein and antibody.Colostrum also contains immunoglobulin (Ig) (as IgG) and the growth factor of high concentration.Condensation and the loss that pasteurize can cause immunoglobulin (Ig) is carried out to colostrum.About 25% ~ 30% of the IgG concentration in first Ruzhong is damaged in the hot pasteurize of colostrum and milk.Therefore, hot pasteurize is in general favourable, but has adverse effect to milk and colostrum.Colostrum is reheating and freezing before breast-feeding, bottling and storage usually.
Ultraviolet pasteurizer also can be used for processing milk.The United States Patent (USP) 6 of the people such as Rix, 916,452 disclose: before milk being delivered to refrigerating plant and milk storage bucket in bulk, one or more UV sterilizer unit can be used while milk temperature being kept above 82.4 ℉ (28 DEG C) to carry out sterilization to milk in milk plant.Such pasteurizer is conceptually very rational, but it can not separately in milk plant's equipment because its lack for the preparation of distribute for milk and hello to the milk of newborn animal and the necessary key function of colostrum.
Need successful kill harmful bacterium but seldom or not destroy the pasteurization system of the improvement of the immunoglobulin (Ig) for optimizing newborn animal health.
Summary of the invention
The present invention relates to the system and method for carrying out pasteurize to the milk and/or colostrum of feeding newborn animal.Term used herein " milk " should be understood to comprise milk, colostrum, other newborn animal feed and any relevant additive." newborn animal " used herein comprises any milk plant animal such as milk cow, goat and sheep.
This system comprises: for storing the bucket of milk or colostrum; Circulating pump and pipe-line system; For regulating and/or keep the heat exchanger of milk temperature; And ultraviolet light pasteurize unit (" UV reactor ").Controller makes pump startup so that milk is circulated to heat exchanger, thus by milk temperature rise to 85 ℉ ~ 120 ℉, then warm milk is passed through UV reactor with kill harmful bacterium with suitable speed and frequency cycle.Then, milk can be frozen and store or directly feed to newborn animal.By milk temperature being only increased to the scope of 85 ℉ ~ 120 ℉, to the destruction much less of immunoglobulin (Ig) and milk has still carried out pasteurize safely by the UV light from UV reactor.
Be different from discontinuous pasteurizer, the temperature that UV reactor does not rely on milk carrys out kill bacteria.In fact, the independent UV light kill bacteria in 200 ~ 280 nanometer range (i.e. UVC scope (bactericidal range)).But milk temperature is important, because cold milk is stirred (churn) by pump and pipe-line system, the butter slices (butter flake) being difficult to fully be processed by UV light can be formed.By milk temperature rise to 85 ℉ or more your pupil melt to make formed butter slices or reduce its size, thus by UV reactor, milk fully to be processed.Preferably, by milk temperature rise to more than 95 ℉ and more preferably to more than 100 ℉ to guarantee the suitable milk viscosity under minimum milk oil concentration.On the other hand, milk is heated to too high temperature and can destroys useful immunoglobulin (Ig).The upper limit of the minimized temperature range of the destruction of immunoglobulin (Ig) is made to be 120 ℉, to be preferably 115 ℉ and to be more preferably 110 ℉.
The temperature range of about 85 ℉ ~ about 120 ℉ comprises the nursing temperature range of about 100 ℉ ~ about 110 ℉.If directly fed to newborn animal by milk, be then heated to the nursing temperature range of about 100 ℉ ~ 110 ℉, because the pasteurize carried out is suitable.
If milk is frozen and stores after pasteurize, then will obtain sufficient result according to the present invention in the milk temperature compared with low side of 85 ℉ ~ 120 ℉ scopes and reduce energy demand.Note, treated useless milk may need to flow to the place that newborn animal in milk plant is stayed.In this case, milk is heated above nursing temperature range and can compensates the cooling of milk when it is carried.Heat loss is with environmental condition, time between pasteurize and feeding and other factors change.Therefore, adopt the present invention, adjustable milk temperature is with these factors in any specific milk plant situation of compensation and other factors.
